| Somusen LS LT Heater Core Bypass Delete Hose | Somusen | LS/LT engine compatibility |
| PIT66 Heater A/C Delete Panel | PIT66 | 3rd Gen C/K Truck compatibility |
| AIB2C Heater Core Delete Bypass Hose | AIB2C | LS/LT series engine bypass |
G-PLUS Heater A/C Delete Panel for G-Body Cars

The G-PLUS delete panel is designed for 1978-1988 G-Body models such as the Monte Carlo, Malibu, Cutlass, and Regal. Built with durable materials, it aims to reduce the need for heater core components and simplify under-dash routing. Its compatibility with classic body styles offers a clean, OE-like replacement experience while helping reduce heat-related maintenance intervals. The panel emphasizes durable construction to withstand long-term use and minimize future replacements.
ZTUOAUMA 25mm Air Intake Pipe Hose with Filter

Designed for diesel heater systems, the ZTUOAUMA kit features a 25mm air intake pipe and filter with clamps. It is compatible with Eberspacher Webasto Airtronic models like D2, D4, and D1LC, plus universal 2kW and 5kW Chinese heaters that use a 25mm intake. The kit provides staged lengths—44 cm compressed and 64 cm stretched—helping users tailor piping to engine bay layouts. This option suits builds where the intake path needs reliable, vibration-resistant tubing and a compatible filter to maintain airflow integrity.
Somusen LS LT Heater Core Bypass Delete Hose

The Somusen bypass hose targets GM Chevy LS/LT engines and their numerous variants (LS1, LS2, LT1, LT4, LT5, etc.). It enables a heater core bypass by looping heater outlets at the water pump, using 5/8″ and 3/4″ hose ends for broad compatibility. The hose is engineered for high strength and long lifespan, backed by clamps for secure connection. This option is favored in swaps where heater functionality is unnecessary but a leak-free bypass is required to maintain cooling system performance.
PIT66 Heater A/C Delete Panel for Chevy/GMC 3rd Gen C/K

The PIT66 delete panel is tailored for 1973-1987 Chevy and GMC 3rd Gen C/K trucks. It features 6061 aluminum construction for durability, with OE-standard fitment to withstand the rigors of under-hood environments. The panel provides a clean, robust alternative to stock heater components, reducing complexity and potential failure points while maintaining the truck’s original appearance and fitment accuracy.
AIB2C Heater Core Delete Bypass Hose for LS/LT engines

The AIB2C bypass hose is designed for LS/LT series engines, offering an aftermarket coolant bypass that eliminates heater core reliance while preserving overall cooling system integrity. The kit includes one hose and two clamps, with a focus on durability through robust rubber material. It serves as a straightforward solution for eliminating heater core flow in performance builds or swaps lacking traditional heater routing, while ensuring reliable cooling system operation.
Buying Guide
- Vehicle compatibility: Confirm year range and engine type (G-Body vs LS/LT swaps) to ensure the delete panel or bypass hose fits without modification.
- Material and durability: Look for aluminum panels or reinforced rubber hoses designed for long service life and resistance to heat, oil, and vibration in a typical engine bay.
- Installation considerations: Some delete panels require simple mounting, while bypass hoses depend on hose size compatibility (5/8″ or 3/4″ ends) and clamps for a secure seal.
- System impact: Deleting heater cores may affect cab heat and defrost functionality. Plan for alternate heat sources or driver comfort if necessary, and verify that the cooling system remains properly pressurized and leak-free after installation.
- Future maintenance: Consider parts availability and ease of replacement. Aluminum panels generally resist corrosion, while hoses should be rated for automotive coolant temperatures.
- Warranty and compatibility notes: Check product descriptions for OE-standard fit and any installation constraints for your specific model year and engine setup.
